Simon,
I removed the ExternalIP and ExternalIsDynamic and DefaultDomain
settings and the suspect endpoints register fine now, so Problem 1 solved!
Whats more, I can place calls from LAN to WAN no problem.
Problem 2 still exists, I cannot get calls from WAN to reach LAN
endpoints. This also affects the catchall/receptionist scenario I am
looking for.
I have moved DNS to the front of the routing policy and removed the
Cname records for the extensions in the DNS records.
When I make a call to user@xxxxxxxxxxxxxx or 1234@xxxxxxxxxxxxxxx or
even just mydomain.co.za or xxx.xxx.xxx.xxx I cannot see anything
happening in the trace on gnugk even though AcceptUnregisteredCalls=1
and AcceptNonNeighborLRQ=1
How do I see if an external call is hitting the gnugk?
Any other pointers? seems I am almost there...

Problem 1:
You will need to post the contents of the GCF message to determine whether
the correct IP address is being sent in the GCF. What is the internal
network mask? 192.168.1.0:255.255.255.0 ? This is important as the
gatekeeper uses the routing table to determine whether the received address
to internal or not. If the internal address in not in the routing table for
the internal network then it will send the external IP (this is a known bug)
You may need to add a route to the routing table so the gatekeeper knows
that 192.168.1.70 is internal.
You should only need 1 NIC and IP address.
Problem 2:
I suggest you remove
[Gatekeeper::Main]
DefaultDomain=mydomain.co.za
External calls to user@xxxxxxxxxxxxxx should then connect to "user"
registered on the internal LAN. The way it is it looks for
"user@xxxxxxxxxxxxxx" which of course it can't find.
Your assumptions are correct and it should all work.

Subject: Proxy and a single NIC? CatchAll
Scenario:
======
I have an ADSL line with a dynamic public IP and a dyndns address for it.
I have my gnugk running on a single NIC with an internal IP address
192.168.1.15
I have my gnugk in the DMZ of the ADSL router and have done port forwarding
to it.
I have my endpoints registered and calling between them.
T_120 Always On tcp 1503 - 1503 1503 - 1503 192.168.1.15
H_323 Always On tcp/udp 1718 - 1721 1718 - 1721
192.168.1.15
H245_Q931 Always On tcp 30000 - 32000 30000 - 32000
192.168.1.15
RTP Always On udp 1024 - 60200 1024 - 60200 192.168.1.15
Problem 1:
=======
The moment I add the lines below for external calls, a few of my endpoints
suddenly cannot register and get the messages below that:
ExternalIP=mydomain.co.za
ExternalIsDynamic=1
2009/10/27 11:09:06.644 2 RasSrv.cxx(175) RAS Read from
192.168.1.70:1719
2009/10/27 11:09:06.645 2 RasSrv.cxx(226) RAS Received GRQ from
192.168.1.70:1719
2009/10/27 11:09:06.645 1 RasSrv.cxx(354) RAS GRQ Received from
192.168.1.70:1719
2009/10/27 11:09:06.646 2 RasSrv.cxx(394)
GCF|192.168.1.70|5678|terminal;
2009/10/27 11:09:06.646 2 RasSrv.cxx(238) RAS Send GCF to
192.168.1.70:1719
The systems that fail after I add the lines are Aethra Maia XC and Aethra
Vega X3 running version 1.5.23 and 12.1.10 software respectively.
Q> Does this mean that in Proxy mode the gatekeeper needs two NICs, one
facing the external network and one facing the internal private side?
I assume this will cure the endpoints failing to register.
Problem 2:
=======
I am using Polycom PVX internally and can do calls to an external IP
just fine, but external systems cannot call into my internal endpoints.
Here is my config:
[Gatekeeper::Main]
Fourtytwo=42
TimeToLive=60
ExternalIP=mydomain.co.za
ExternalIsDynamic=1
DefaultDomain=mydomain.co.za
[RoutedMode]
GKRouted=0
H245Routed=0
AcceptUnregisteredCalls=1
Q931PortRange=30000-30999
H245PortRange=31000-31999
[Proxy]
Enable=1
ProxyAlways=1
InternalNetwork=192.168.1.0/16
T120PortRange=50000-59999
RTPPortRange=1024-65535
ProxyForNAT=1
[GkStatus::Auth]
rule=allow
[RoutingPolicy]
default=explicit,internal,dns,catchall
[Routing::CatchAll]
CatchAllAlias=1234
[RasSrv::LRQFeatures]
AcceptNonNeighborLRQ=1
[RasSrv::RRQFeatures]
SupportDynamicIP=1
The moment I enable GkRouted or H245Routed in [RoutedMode] nothing works.
Do I need to modify my CName DNS records to point to my extensions like so:
1234@ points to mydomain.co.za
At the moment if I call from an external unregistered public IP to any
of my extensions I get a "No route to destination" message.
Once this is all working:
===============
I assume that external unregistered callers will be able to call to any
of the internal extensions by using extension@xxxxxxxxxxxxxxx
I'd also like to send all incomming calls to mydomain.co.za to a
specific extension specified in the CatchAllAllias setting to create a
receptionist effect.
I have been battling this one for a week now. Any help or guidance will
be rewarded.
